Busch R5 Series Oil Change Walkthrough

Busch R5 Oil Change Walkthrough

Basics of a Busch R5 Oil Change

Today, we share our expertise in a Busch R5 oil change. This article is a Busch R5 Series Oil Change Walkthrough. In this article, we will be showing the oil change on a PRS Mini Series Rollstock machine. The pump we are changing the oil on is a Busch R5 RA 0040 F oil-lubricated rotary vane vacuum pump.

Before we get knee-deep in this job, please make sure to gather the tools you need from the list below as well as make sure you have enough time to finish the job. Typically these rollstock thermoformers are used very heavily and most facilities can not afford too much downtime. This job is very simple and strongly urge training up a few people in your facility to tend to this matter as needed. So let’s get started with what you will need to get the job done.

Difficulty Level: Easy

Time Required: 15-30 minutes

Tools Required: Busch OEM oil or JVR VacOil, Busch oil filter, filter wrench/pliers, funnel, and chamber vacuum pouch/drain pan,

The following instructions are applicable for any R5 series of Busch vacuum pumps.

Essential tools for the job include a filter wrench and a funnel. These two tools alone will work in almost any application. If you do not have a filter wrench, you can use pliers instead. Also, have something to catch the oil during the draining process. JVR suggests using a chamber vacuum pouch for easy drain and clean up after the job is completed. If you do not have chamber vacuum pouches at your disposal, a simple drain pan will work just fine. Now you will need the heartbeat of the operation: vacuum pump oil. You can use Busch OEM oil or JVR’s line of VacOil during this process.

Draining the oil from Busch R5

Every Busch vacuum pump is going to have a drain plug. It’s typically located on the fan side of the module. The lower plug is always going to be the drain. The upper plug will be the fill, and in the middle, you have a sight glass. This will tell you at what point you need to fill your oil.

Take your pair of pliers and loosen up the drain plug. Before you loosen the plug completely, get something to catch the oil. Depending on the location of the pump and oil drain, traditional drain pans may not provide the best oil-catching configuration. Chamber pouches work great in many applications because they’re flexible but thick enough that you won’t have leaks.  

Push or scrunch the bag partially under the vacuum pump to completely catch oil from the drain. Once your bag is in place, spin the plug out with your fingers. Make sure you don’t let the plug drop into the chamber pouch. After the oil starts flowing, continue to hold the pouch or pan in place as the oil drains.  

Once the oil slows to a trickle and is no longer draining, you can rethread the drain plug and hand tighten it for now so you can move the oil-full bag or pan. Please note: every drain plug has an O-ring around it. Make sure the O-ring is in the proper groove of the drain plug before reinsertion.  

If you’re using a chamber vacuum pouch to catch the oil, give it a good twist, and even knot the bag if you have enough room. Otherwise, you can use a few zip ties to tighten the bag closed. Now you can dispose of the oil in a responsible manner. Grab your pliers again and finish tightening the oil drain plug.

Go ahead and tighten up the oil drain plug with your pliers. Do not overtighten the drain plug because it is made of plastic. About 1/8 of a turn should be relatively sufficient after the plug was hand-tightened.

Busch Pump Filter Change

To change the oil filter, you’ll want to use a filter wrench. If one is not available, you can use a pair of pliers. If neither of these tools is available, you can use a flathead screwdriver, although this is for desperate situations. Pound the screwdriver through the center side of the filter. Then you can turn the filter using the screwdriver.

Once the oil filter is partially loose, grab a chamber pouch or pan. It can be the same one used previously if you have enough room. Cup the bag underneath the filter and under the pump a little. When you begin loosening the last few threads, you’ll see the oil draining out. Make sure you hold the bag tight in place, so it doesn’t make a mess.  

At this point, if you have a helper, they can hand you the new oil filter. If you’re working on your own, ensure the new oil filter is nearby before you start the process. While still holding the oil drain pouch in place, grab a small amount of oil on your finger and rub it around the gasket of the new oil filter. This allows the new oil filter to go on smoothly to get the proper torque. Now you can thread on the new oil filter. Tighten the filter just enough for the oil to stop dripping. Pull the drain pouch away and responsibly dispose of the oil as we mentioned previously.  

After you dry off your hands of oil residue, wipe off the filter and once the gasket touches, give it about a three-quarter turn as tight as you can by hand. Don’t use a filter wrench or pliers to tighten it because that will make it more difficult to remove next time.  

If you’re not sure if the oil filter is on tight enough, run your pump for an hour or so. Then inspect underneath the filter. If you see an oil drip, you’ll need to tighten up the filter a little bit.  


For a vacuum pump that’s 2 HP or above, we recommend using the #46 VacOil. For pumps smaller than 2 HP, we recommend using the #22 VacOil. Additionally, we have a line of synthetic oils perfect for use in an extreme duty or cold room where your machine is running for extended periods of time.  

Filling the oil

Return to where we previously drained the oil. Remove the fill plug with your pliers and insert a funnel. Grab your favorite vacuum pump oil. For our oil change on the Busch R5 Series RA 0040 F pump, we are using a #46 JVR VacOil. Grab your funnel and place it in the fill of the pump. Fill the pump with oil until the level reaches three-quarters full in the sight glass, or until there’s only a slight bubble at the top. On many Busch pumps you’ll notice maximum and minimum fill lines. When you go to run the pump, the oil level is going to decrease slightly because the oil fills up the filter and circulates through the system.

After the filling is complete, grab your fill plug. First, make sure that your fill plug has the o-ring still in place. Second, reinsert the fill plug and hand tighten. Once hand-tightened, grab your pliers to give the fill plug a final 1/8 of a turn to snug it down.

Random Repeat VS Registered Printed Film

Registered vs Random Repeat Rollstock Film

Registered vs Random Repeat Custom-Printed Rollstock Film

Today, we will discuss the differences between registered and random repeat custom-printed films for rollstock packaging. Our customers often seek further clarification on these terms and how they compare. Let’s explore the characteristics of these two types of custom-printed thermoforming packaging films.

PRS Mini - VacForm Forming Film
Registered Print Example

Registered print is a straightforward printing method where the artwork repeats at the same distance as the cutting tool. For instance, if the cutting occurs every 200mm, the artwork will repeat in 200mm increments on the rollstock unit. This type of printing is ideal for customers with larger volume orders requiring more information on each package. Registered print has a visually appealing quality and is similar to labeling. Customers transitioning from labels to registered print find the process seamless. However, this type of print demands meticulous attention to detail and precise operation of the rollstock thermoforming equipment. It requires an operator with a keen sense of quality.








Random repeated custom-printed rollstock film is when you set up artwork to repeat in a patterned sense. The artwork does not seem random, but the cutting time is random. For example, your artwork could repeat at 200mm, but your unit could be cutting your film every 120mm. Your final package will seem as if the print is random, but ultimately it is your cutting that is random relatively speaking. See the reference image where the film behind the sealed product has a repeating leaf.

Random Repeat Print Example






Registered vs Random Repeat
Random Print Film Comparison

Random repeat print is quite simple to set up. Typically you need to set up per the width of your roll multiplied by how many lanes are being printed. As far as the advance, you will need the plate size from the printer. All of this information is readily available upon request.

Registered Film Comparison

The registered print will need to be set up off of the die file provided by the manufacturer of your thermoforming vacuum packaging machine. You need pocket length, pocket width, pack width, top film (non-forming) width, and advance length (repeat length). Usually, the die file will provide all of this information making it easier to forward off to JVR Industries. We require our customers to only send a 1-up file and we can step out the artwork and apply the required distortions for proper printing.

JVR Industries can use pre-existing files such as .ai, .pdf, .psd, and .jpeg. The file type we require for your specific job depends on what you require of us. If you are looking to just print the file you have, then we need a workable file such as an adobe illustrator file or illustrator pdf file. In the event that your text needs to be edited, we will need the text to be live in the file.

Looking for a brand-new design? No problem! You can leave that up to our in-house graphic designer/prepress technician to tend to. Lastly, if you are considering a recreate, we need any file type. Flattened files like .jpeg might work but depends on the specific scenario. Please feel free to reach out to andrew@jvrinc.com for any custom printed rollstock thermoforming vacuum packaging film requests.

Selecting the type of printing is all dependent on your personal preferences and needs!

Typically, random repeat printed bags only use one color of ink like black. It is not uncommon for customers to use this for things like bio-hazard, recycling, or suffocation warning symbols. Often times this type of printing is so our customers can meet the standards or requirements in their industry.

If you have any further questions, please feel free to call our offices in Lancaster, NY.

Rollstock seal bar types

Rollstock Seal Bar Types

Rollstock Seal Bar Types

Rollstock thermoforming vacuum packaging machines host two different sealing plates within the sealing head of the unit. The two types of seal bars are the total seal plate and the perimeter seal plate.

Rollstock sealing head

Total seal plates offer a comprehensive sealing solution by applying pressure and heat to the entire package, making it a universal option. In contrast, the perimeter seal focuses specifically on the outer borders, which limits its compatibility with certain seal grids.

Under the seal head is where the seal bar is located. Here you can select two different style seal bars for two different applications. See below for a brief overview for each seal type.

Perimeter Seal Bar Plate

Perimeter Plate - Rollstock

Outer perimeter heat sealing is the only option on a perimeter seal. This eliminates the risk of searing and provides an easier-to-open package. For this option, a different seal bar is required for each configuration.

Total Seal Bar Plate

Apply heat to the entire surface of the plate using total seal plates. The lower seal grid will determine the primary seal location. All remaining areas where the top and bottom film touch will receive a secondary seal. This type of seal bar will work with all configurations, but the downside is that the risk of searing fresh products is increased.

We created these simple visuals to help identify and understand both the naming convention and basic functionality of these rollstock major components. Understanding the major components of a thermoformer can help you to operate and maintain your unit appropriately. Maintaining your unit requires proper identification. Simple identification helps in ordering the parts and communicating failures well to encourage proper diagnosis. Let’s get into each station and the major components attached to each station.

Compressed air or vacuum forces the forming film against a hot plate and then draws it into a mold to create formed pockets.

Rollstock Sealing FIlm

The sealing film (VacSeal) is the top film that is introduced to close off the bottom film while simultaneously removing up to 99.8% of the air out of the pouch for longer shelf life.

Valves open allowing a vacuum pump to draw air out of the cavities. Introduced gas mixture comes next, if applicable. Heat seal the top film to the bottom, creating an air-tight package in the final stages.

Rollstock Sealing Station Head

Sealing Head

Under the seal head is where the seal bar is located. Here you can select two different style seal bars for two different applications.

Rollstock Rotary Crosscut

Divide film into individual packages using crosscut (left) and rotary knives (right).

Trim Scrap Removal

The rotary knives trim off the outer edges of the film. 2 types of trim scrap removal are commonly used: vacuum or rewind removal. Collect the film trim using the vacuum or rewinding system.

What is a Rollstock Machine?

What is a Rollstock Machine?

“…a horizontally configured packaging machine.”

A very common question for us to receive is: “What is a Rollstock Machine?”

Today, we will answer that question simply!

After inserting the product, the operator heat seals a non-formed top layer of film onto the pockets, creating an airtight package. Upon exiting the seal region, the operator can use crosscut and rotary knives to trim and refine the packaging, ensuring a clean and professional look.

Additionally, these rollstock thermoformers, also known as HFFS (Horizontal Form Fill Seal) units, significantly improve efficiency and result in visually appealing packaging. By using a rollstock machine, businesses streamline their packaging process, enhance productivity, and achieve captivating product presentations.
